How to grow Geranium Horizon Mix seeds

Choose Your Planting Method

Prepare Your Materials

• Seed-starting trays or pots
• Well-draining seed-starting mix
• Plastic wrap or a humidity dome (to hold in moisture until sprouting)
• Spray bottle for misting

Sowing the Seeds

• Sow about 1/8 inch deep and cover lightly with mix or vermiculite; light is not required for germination.
• Keep the mix evenly moist but not soggy.

Provide the Right Conditions

• Light: Give seedlings bright light as soon as they emerge.
• Temperature: About 70-75°F (21-24°C) for germination.
• Humidity: Cover the tray until seeds sprout, then remove the cover.

Germination

• Seeds sprout in 7-14 days at warm temperatures.
• Transplant seedlings to small pots as soon as they can be handled.

Transplanting

• Harden plants off gradually, then set out after all danger of frost has passed.

Care Tips
